Anyone who tells you have a purpose in life is wrong. You don't. None of us. That is a belief sold to you, so that you spend your entire life searching for some nonexistent purpose and beating yourself up when you don't find it.
You don't come to this life with a purpose, you make a purpose. When you come, your life is essentially meaningless but you give it meaning. You chose what your life means and you can change that as much as you like, whenever you like.
And isn't that even more beautiful? Isn't that more beautiful than having some stupid destined purpose that you didn't even get to choose for yourself but must keep chasing your entire life. Is it not more beautiful that you decide for yourself what that meaning is, that it is up to you to decide the things and people that give your life meaning, it is up to you if you want to do something extraordinary in your life or if you're fine with a quiet one. Both are equally as valid, as long as they make you happy.
It's enough to just exist, to just be. You are enough just by existing. No one should tell you otherwise, you don't need to prove your existence, you don't need to have a purpose. It's enough to just exist, to just be. It's enough to just be alive and standing, you don't need to do anything extraordinary to prove that.
It is enough to just exist and it is up to you and you solely to give your life the meaning and purpose you want it to have. That's what being alive means.
Tl;Dr: Life doesn't really have a purpose, you don't have anything to prove. It is enough to just be alive and you give your life meaning, not anyone else.
